Embodiment 1

[0067] Example 1: 5-20°C natural room temperature, GA 3 800mg / l under the sand for 90 days, with GA 3 Soak at 800mg / l for 2 minutes, put it in a 4°C incubator for 10 days, then plant it in a nutrient bowl, and move it into an intelligent greenhouse.

[0068] Embodiment one detailed process:

[0069] 1.1 Disinfection: Soak the seeds of peony purpura with 0.4% potassium permanganate (the purity of potassium permanganate is AR grade) for 2 hours, stir continuously during soaking, and rinse repeatedly with clean water after 2 hours to clean the peony purpura seeds.

[0070] 1.2 Soak in clear water for 3 days: Pour 50°C clear water into the pot containing the peony seeds, stir for a while, and when the temperature drops to about 20°C, move the pots containing the peony seeds into a constant temperature and humidity incubator. Set the temperature at 25°C, stir once every 4 hours during 3 days, change the water every other day, and use tap water for subsequent water changes without...

Embodiment 2

[0075] Example 2: 15°C temperature incubator, GA 3 300mg / l coconut peat matrix for 90 days, with GA 3 Soak at 800mg / l for 2 minutes, put it in a 4°C incubator for 10 days, then plant it in a nutrient bowl, and move it into an intelligent greenhouse.

[0076] Embodiment two detailed process:

[0077] 1.1 Disinfection: Soak the seeds of peony purpura with 0.4% potassium permanganate (the purity of potassium permanganate is AR grade) for 2 hours, stir continuously during soaking, and rinse repeatedly with clean water after 2 hours to clean the peony purpura seeds.

Abstract

The invention discloses a method for improving the paeonia rockii seed emergence rate. The method comprises the following steps of using natural room temperature of 5 to 20 DEG C; soaking paeonia rockii seeds by GA being 3800 mg / l for 72 hours; then, performing sand storage for 90 days; soaking the rooting paeonia rockii seeds by the GA being 3800 mg / l for 2 min; putting the soaked paeonia rockiiseeds into a culture box with the temperature being 4 DEG C for 10 days; then, planting the seeds into a nutrition pot; transplanting the culture pot into an intelligent greenhouse. Compared with theprior art, the method has the advantages that the emergence rate of the paeonia rockii seeds can be improved, so that the seeds can become high-quality seed seedlings; endangered breeds can be rescued; the yield can be expanded; the popularization and application values are realized.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving the germination rate of peony seeds. Background technique [0002] Purple spot peony (Paeonia suffruticosa Andr.var.), belongs to the Paeonia genus of Ranunculaceae. Distributed in northern Sichuan, Gansu, and southern Shaanxi. Growing in thickets on hillsides at an altitude of 1100-2800 meters. It is named for the dark purple spots at the base of the inner surface of the petals. The leaves are two to three times pinnately compound, the flowers are large and the petals are white. In 1987, it was listed as a national third-class protected plant. Included in "China Red Data Book ----- Rare and Endangered Plants". [0003] Purple spot peony is a unique species in China, scattered in Gansu, Shaanxi and other places in my country. It is a traditional endemic species in Northwest China. In Gansu Province, it is distributed in Ziwuling and Xiaolongsha...
